(Journal article; Tidsskriftartikkel; Peer reviewed; Preprint; Manuskript, 2017-07-01)
      Adequate intake of copper and zinc, two essential micronutrients, are important for antioxidant functions. Their imbalance may have implications for development of diseases like colorectal cancer (CRC), where oxidative stress is thought to be etiologically involved. As evidence from prospective epidemiologic studies is lacking, we conducted a case-control study nested within the European Prospective ...

      Muller, Ashley Elizabeth; Ormstad, Sari Susanna; Jardim, Patricia; Johansen, Trine Bjerke; Berg, Rigmor (Research report; Forskningsrapport, 2020-03)
      Remote patient monitoring (RPM) allows for the real-time transmission of health data, evaluation of this data, and appropriate follow-up. This allows providers to monitor the health status of chronically ill patients and quickly adjust treatment regimes, without requiring that patients continually visit providers’ offices.<p><p> We summarized systematic reviews of a specific type of RPM that the ...

      Møllersen, Kajsa; Hardeberg, Jon Yngve; Godtliebsen, Fred (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-26)
      Multi-instance (MI) learning is a branch of machine learning, where each object (bag) consists of multiple feature vectors (instances)—for example, an image consisting of multiple patches and their corresponding feature vectors. In MI classification, each bag in the training set has a class label, but the instances are unlabeled. The instances are most commonly regarded as a set of points in a ...

    • Lifetime ultraviolet radiation exposure and DNA methylation in blood leukocytes: The Norwegian Women and Cancer Study 

      Page, Christian; Djordjilovic, Vera; Nøst, Therese Haugdahl; Ghiasvand, Reza; Sandanger, Torkjel M; Frigessi Di Rattalma, Arnoldo; Thoresen, Magne; Veierød, Marit Bragelien (Journal article; Tidsskriftartikkel, 2020-03-11)
      Ultraviolet radiation (UVR) exposure is a leading cause of skin cancers and an ubiquitous environmental exposure. However, the molecular mechanisms relating UVR exposure to melanoma is not fully understood. We aimed to investigate if lifetime UVR exposure could be robustly associated to DNA methylation (DNAm). We assessed DNAm in whole blood in three data sets (n = 183, 191, and 125) from the Norwegian ...

    • Associations between utilization rates and patients’ health: a study of spine surgery and patient-reported outcomes (EQ-5D and ODI) 

      Rudolfsen, Jan Håkon; Solberg, Tore; Ingebrigtsen, Tor; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-22)
      <i>Background</i> - A vast body of literature has documented regional variations in healthcare utilization rates. The extent to which such variations are “unwarranted” critically depends on whether there are corresponding variations in patients’ needs. Using a unique medical registry, the current paper investigated any associations between utilization rates and patients’ needs, as measured by two ...
